Abstract (en)

[origin: EP0847025A2] When an information signal recorded in a magnetic card is updated by an information recording and updating apparatus, a spectrum spread signal corresponding to the updated information signal is generated and it is then recorded superimposing to the information recorded previously in the magnetic card without erasing the old information. Since the information is spectrum spread, alternation is difficult. Moreover, the magnetic card may be discriminated whether it may be used or not by considering the old information recorded in the magnetic card when it is used. <IMAGE>
